7/8-inch from the edge of the ash pan with its leading
end even with the front screw post. The whistle switch
is mounted 3/8-inch from the edge of
the ash pan also with its leading end
even wit h t he fro nt po st . This
placement allows clearance on the
underside of the PC board.
4.
A group of engine wires extend from the
electronic board in the ash pan to the tender. This group of wires is covered by
a black plastic molding that is fastened to the underside of the engine by two phillips
head screws, one near the ash pan on the bottom of the engine and the other
(topside) inside the coal bunker on the floor. The wires from the two reed switches
can be concealed by running them along with the Shay engine wires inside this
molding.
5.
Radio Shack magnets, model 64-1879, are 3/16-inch thick.
In order to bring the height on the magnet flush with the top
of the rail, add a 3/16-inch spacer to the bottom of the magnet.
The spacer may be wood, plastic, or any other material that
will do the job.
6.
Magnet 64-1879 should be located 3/16" from
the rail on top of the tie, as shown in the sketches.
7.
For Radio Shack model 64-1883 magnets, place two
together and add a spacer of approximately 3/16-inch to
make the stack even with the top of the rail.
